Dirichlet-Neumann waveform relaxation for heterogeneous heat equations: continuous and time discrete L2 analysis
Niklas Kotarsky, Philipp Birken, Martin J. Gander +1
We consider two coupled linear heat equations on different spatial domains that interact through a lower dimensional interface. This models conjugate heat transfer. The problem is…

A time adaptive multirate Quasi-Newton waveform iteration for coupled problems
Niklas Kotarsky, Philipp Birken
We consider waveform iterations for dynamical coupled problems, or more specifically, PDEs that interact through a lower dimensional interface. We want to allow for the reuse of ex…
